The SummaryTyphoon Ivy (international code 196511) is a 1965 Northwest Pacific typhoon; peak intensity Typhoon, max wind 41m/s, minimum central pressure 990hPa, not in China Landfall, 1965-07-31 was numbered off, recording 19 track points.
Typhoon Ivy, international code 196511, international name IVY, 1965 Northwest Pacific typhoon. Formed: 1965-07-27 06:00:00, ended: 1965-07-31 18:00:00. Peak intensity: Typhoon , minimum central pressure: 990 hPa, max wind: 41m/s.
Typhoon Ivy at 1965-07-27 06:00:00 at 14°N, 131.9°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 41 m/s (~148 km/h) and a minimum central pressure of 990hPa, recorded at 1965-07-30 06:00:00.
1965-07-31 18:00:00 After, Typhoon Ivy gradually weakened and was numbered off on 1965-07-31 18:00:00 was numbered off; its lifecycle recorded 19 track points.
Typhoon Ivy (196511) 的生命史始 at 1965年7月27日06:00, 初始Position位 at lat 14.0°N, 131.9°附近, formed时为Nameless. 在生命初期, 系统呈现明显的W行Trend, 从131.9°E迅速Moving至125.8°E附近, The latitude基本维持在13.8°N至14.9°N的狭窄带状区域内. 值得注意的是, 该Typhoon 在7月29日至30日期间出现了一次显著的“折返”现象. 在7月29日12:00到达最W端 (126.7°E, 14.5°N) 后, 路径并未继续 toward W深入, 而是先短暂S压, 随后 at 7月30日06:00开始转 toward NE. 这种先W行, 后停滞, 再折 toward NE的路径形态, 表明其受到副热带高压边缘气流引导及可能的中纬度槽前气流影响, 导致Moving direction发生剧烈调整. 最终, 系统 at 7月31日18:00 at 17.1°N, 132.1°处结束观测, 全程无Landfall记录, 主要活动海域集中在Philippines以E洋面.
在Intensity变化方面, Ivy经历了快速增强, 波动维持及二次加强的过程. formed后仅18h, 即由Nameless发展为Tropical Storm, 并 at 7月28日00:00 intensified into Typhoon (33m/s) . 在7月28日至29日期间, intensity 维持在30-35m/s之间, 期间曾短暂 weakened into Severe Tropical Storm. 然而, 在路径折返过程中, 系统 at 7月30日06:00达到peak intensity, max wind 录得41m/s. 此后Intensity虽有小幅波动, 但直至消散前仍保持Typhoon 级别 (35-38m/s) , 显示出较强的生命力.
The data showed that the 1974 (197411) and 1977 (197715) same-name Typhoon peak intensity both reached the 'Severe Typhoon' level, and 1971 (197111) was the 'Severe Tropical Storm'. 1965 Ivy's peak intensity was only 'Typhoon' level (41m/s) , failed to reach the Severe Typhoon standard, but its continuous Time and path complexity has some representation in the same name sequence.
